A parallel plate capacitor has a common plate area of 5 x 10-8m2 and plate separation of 2 x 103m, Assuming free space, What is the capacitance? [(varepsilon)o = 9.0 X 10-12C2N-1m-2]
-
A.
2.25 x 10-17F -
B.
4.50 x 10-17F -
C.
2.25 x 10-16F -
D.
4.50 x 10-16F
Correct Answer: Option C
Explanation
C = (frac{{varepsilon}_oA}{d})
= (frac{5{times} 10^{-8} {times} 10^{-12}{times} 9}{2 {times}10^{-3}})
= 22.5 x 10-17F
